Castrol Braycote® 601 EF

Technical Data Sheet


Chinese


Description
Castrol Braycote® 601 EF is a smooth, buttery, translucent, off-white, NLGI #2 grease. Its base oil (Castrol Brayco® 815Z) is a perfluorinated polyether, with exceptional chemical resistance, extremely low volatility, and a wide temperature service range. The grease is non-toxic, nonflammable, and does not use any chlorofluorocarbons (CFC's) during product manufacture. Castrol Braycote® 601 EF exhibits unusually high load-carrying capabilities as measured by the Four-Ball EP Test, and contains a rust and corrosion inhibitor for extra component protection. Castrol Fluoroclean™ X100 or Castrol Fluoroclean™ HE can be used to remove this lubricant. Refer to the data sheets for Castrol Fluoroclean™ X100 and Castrol Fluoroclean™ HE for information regarding these products. Castrol Braycote® 601 EF with molybdenum disulfide is also available for applications requiring both corrosion and extreme pressure additives.

Temperature Range
-80°C to 204°C (-112°F to 400°F)

Uses
Castrol Braycote® 601 EF is designed to operate in the presence of rocket fuels and oxidizers and high vacuum. Castrol Braycote® 601 EF is frequently used in space applications including the Space Shuttle and satellites. It should also be considered in any application where a hostile chemical or extreme environmental conditions would preclude the use of an ordinary grease. Typical applications include ball and roller bearings, gears, and as an assembly lubricant for O-rings and elastomers. Perfluorinated greases, such as Castrol Braycote® 601 EF, exhibit excellent shelf life due to their intrinsic inertness.

Limitations
Castrol Braycote® 601 EF is compatible with most commonly utilized materials, plastics, and elastomers. Castrol Braycote® 601 EF may be adversely affected by Lewis Acid Catalysts such as aluminum chloride, at elevated temperatures. Newly exposed rubbing surfaces of aluminum, magnesium and titanium alloys may react with Castrol Braycote® 601 EF under certain conditions. Such systems should be thoroughly evaluated. Surfaces must be well cleaned of organic rust inhibitors prior to grease application to insure proper lubrication. This product is not recommended for use in applications under high vacuum with loads exceeding 100,000 psi for extended periods of time.

Packaging
Castrol Braycote® 601 EF is available in 2 oz and 4 oz (AVDP) disposable polypropylene syringes, 1 lb jars, and 1.75 lb cartridges. A specially prepared "micronic", ultra clean
